To all whom, t 711/07,/ con/cern:

' within the axle-'box a reservoir of oil, into which an endless chain hung on the car-axleV extends and from vwhich it continually raises the lubricant and deposits it on the revolvingaxle as the car to which it is attached is moved.

In 'the accompanying drawings, Figure l represents a vertical longitudinal, section through a car-axle box, showing my invention applied thereto. Figs. 2 and 3 are views in cross-section on the lines 2 2 and 3 3 of Fig. l.

The axle-box as a whole is indicated by A, vinto which projects the end of the axle B, bearing on the brass C, placed, as usual, between the axle and the ltop of the axle-box. The under surface of the brass C is. grooved, as shown at C, to permit an endless chain D, which partly encircles the axle B and hangs downwardly therefrom to travel Vfreely with the axle as it is rotated, but hold it against lateral movement.

Within the axle-box A is an oil-reservoir E, fastened to the bottom of the axle-box bybolts or screws a. The bottom e of the reservoir has a slight downward curvature, so that oil contained in the reservoir will gravitate to the lowest pointnear which the chain D, 'extending into the reservoir, reaches.

Placed transversely across the reservoir E and depending thereinto for some distance is a guard F of flat tubular shape with parallel side walls j andlcurved endwallsf. The object of the guard F is to prevent the chain D serai No. anlass. (Nomade.)

from swinging and from moving laterally as it turns with Vthe axle, a movement which would naturally occur when a car is rounding a curve, as the axles are at such times higher at one en'd than at the other, in which 'position of lthe axles the chains would gravitate toward their lower ends. Apart ofthe guard `F projects above the top e of the reservoir, its

nupper edge f2 being rounded to prevent the chain from being `caught thereon. The lower edge, if desired, may be similarly treated. lThe top e of the reservoir trends in a downward direction from each side toward its longitudinal center, which is left open, as at e?,

so that oil falling from the axle B on the top emay return to the reservoir. The fillingopening for the reservoir at e3 is covered by a cap, as shown, while from the bottom c of the reservoir a drain-cock G extends through the bottom of the axle-box for drawing off all dirt and sediment which may collect therein. A sight-glass H is connected to the front of the reservoir to indicate the height lof oil.

. Having thus described the invention, what is claimedvis- In combination with a car-axle box and an .axle projecting therein, a movable oil-reservoir having a curved bottom, supports for said reservoir, and a top inclining downwardly toward lts longitudinal center, which J.
